Who called from 3475840860

This number has called 3 times today and never says anything. I do not give out my cell phone number and just want to block them!

They have been calling me for the past few days at least three times a day and never leave a message!

I have gotten a call from this number about 3 or 4 times a day, everday for the past week! I haven't answered, because I didn't recognize the number and they never leave a message. What can I do?

I have been getting phone calls every few hrs for the past several days and am getting very annoyed. Hope soemone can make it stop already.

They've called me at least 8 times a day
